TECHNICAL FIELD

The present disclosure relates to mobile communications and relates to,for example, a method, apparatus and device for transporting commoncontrol information.

BACKGROUND

The use of high frequencies (6 GHz to 100 GHz) for communication is oneof the core technical means in the future communication industry.High-frequency communication is one of the developing directions of NewRadio (NR) enhancement. High-frequency communication is characterized bybeing beam-based and tends to use a hybrid beam, that is, a combinationof a radio frequency beam and a baseband beam. One feature of the radiofrequency beam is that one radio frequency link on one OrthogonalFrequency Division Multiplexing (OFDM) symbol corresponds to oneradio-frequency beam direction. Therefore, when different beamdirections are involved, multiple OFDM symbols are needed.

Common control information is transmitted as needed, in which case ascanning beam can cover the entire cell. If the Long Term Evolution(LTE) technology is adopted, only through multiple subframes can thescanning beam cover the entire cell. The transmission beams of multiplesubframes are polled, limiting the scheduling of data signals.Therefore, it is urgent to provide a method, apparatus and device fortransporting common control information to solve the problem in theprocess of transmitting common control information during the precedinghigh-frequency communication.

Embodiment One

In this embodiment, a base station transmits common control informationon M time-domain resources through M transmission resources. Each of thetime-domain resources includes N time-domain symbols. The time-domainresource where the common control information of each transmissionresource is located is determined according to an index of thetransmission resource and a value of N.

The transmission resources include one of more of the following: atransmission beam resource, a transmission antenna resource, atransmission port resource, a transmission frequency-domain resource, atransmission sequence resource and a transmission time-domain resource.

As shown in FIGS. 6a to 6c , the time-domain symbol resourcescorresponding to the same transmission resources are different when thevalues of N are different. The initial time-domain symbol is assumed tobe symbol 0. As shown in FIG. 6a , when the value of N is 1, thetime-domain resource occupied by transmission resource 1 (that is, thetransmission beam group 1 in the figure) is time-domain symbol 1. Asshown in FIG. 6b , when the value of N is 2, the time-domain resourceoccupied by transmission resource 1 is time-domain symbols {2, 3}. Asshown in FIG. 6c , when the value of N is 3, the time-domain resourceoccupied by transmission resource 1 is time-domain symbols {3, 4, 5}.The base station can determine the time-domain resource occupied by eachtransmission resource according to the index of the transmissionresource and the value of N.

The value of N can be determined according to at least one of thefollowing parameters: a system bandwidth, subcarrier spacing, the totalnumber of subcarriers included in one symbol, and the length of thecommon control information.

When the common control information includes a common message and acommon control signaling indicating configuration information about thecommon message, the length of the common control information includesthe length of the common message and the length of the common controlsignaling. The value of N may be carried in a broadcast message. Thevalue of N may be carried in first-level common control information.Optionally, the value of N corresponding to the first-level commoncontrol information which notifies of the value of N is a fixed value,or the value of N corresponding to the system message which carries thevalue of N belongs to a set.

In the above manners of determining the value of N, in the first manner,one value of N is determined; in the second manner, a set B isdetermined in a set A to which the value of N belongs. The set Aincludes two positive integers and the set B is a subset of the set A.The set B includes one positive integer.

When it is determined that N has multiple values, the base station maydetermine the value of N according to at least one of the currentlytransmitted common control signaling and the length of the second typeof common message indicated by the common control signaling. Optionally,the value of N is transmitted to a terminal, for example, by using achannel like a Physical Control Format Indicator Channel (PCFICH) in theLTE or by using the common control signaling. The terminal may determinemultiple values of N by blindly detecting the common control signalingor the common message. For example, the terminal may blindly detect thetransmission manner adopted by the base station in FIGS. 6a to 6 c.

Optionally, as shown in FIG. 7, a one-to-one correspondence existsbetween the M transmission resources and the time-domain resources onwhich a synchronization signal is transmitted, and the terminal obtainsits own optimal receiving manner and a downlink transmission resourceset where the terminal is located through the synchronization signal.The downlink transmission resource set includes at least onetransmission resource. The terminal obtains, according to the index ofeach transmission resource in the transmission resource set and thevalue of N, time-domain symbols on which the terminal detects the commonmessage. As shown in FIG. 7, the terminal receives data in a selectedreceiving manner on C-PDCCH (that is, the common control signaling) andC-PDSCH (that is, the common message) time-domain resources. Forexample, if the set of transmission resources obtained by the terminalis {transmission resource 0, transmission resource 1} and the value of Ndetermined by the terminal belongs to the set {1, 2, 3}, then, for thetransmission resource 1, the terminal detects the common message onsymbols {1}, {2, 3} and {3, 4, 5} in sequence and, for the transmissionresource 0, the terminal detects the common control information onsymbols {0}, {0, 1} and {0, 1, 2} in sequence. In FIG. 7, the value of Nis not fixed and the value of N belongs to a set, so the terminal usesthe same radio frequency receiving manner for different transmissionresources on at least one of C-PDCCH and C-PDSCH time-domain resources.If the receiving manner is a baseband receiving manner, that is,different receiving manners correspond to the same radio-frequency beam,then the terminal can use the same radio-frequency beam to receive alltransmission resources. For each assumed value of N, differenttransmission resources can be received in different receiving mannersthat are previously trained. Optionally, when N is a fixed value, theterminal receives different transmission resources in a specificreceiving manner. For example, if transmission resource 0 corresponds toreceiving manner 1 and transmission resource 1 corresponds to receivingmanner 0 through the previous training of receiving manners, then, inthe C-PDCCH and C-PDSCH, domain transmission resource 0 is received inreceiving manner 1 and transmission resource 1 is received in receivingmanner 0.

In FIG. 7, there are M time-domain resources for the synchronizationsignal, and one time-domain resource on which the synchronization signalis transmitted corresponds to one time-domain resource on which thecommon control information is transmitted (transmission resource isabbreviated as TRS in FIG. 7). Optionally, one time-domain resource onwhich the synchronization signal is transmitted corresponds to multipletime-domain resources on which the common control information istransmitted. Optionally, a one-to-one correspondence exists between theM transmission resources and the M time-domain resources of a broadcastchannel; or a one-to-one correspondence exists between the Mtransmission resources and the M time-domain resources of a measurementreference signal. One time-domain resource of the measurement referencesignal includes at least one measurement reference signal port.

Optionally, in one time-domain resource, a first implementation is toonly transmit the common message, and a second implementation is totransmit the common message and the common control signaling, where thecommon control signaling is used for indicating configurationinformation about the common message. In this case, the common controlsignaling and the common message are in multiplexing mode. In the firstimplementation, as shown in FIGS. 8a to 8b (transmission beam group isabbreviated as TBG in FIG. 8a-8c ), the common control signaling istransmitted on a time-domain symbol having the smallest index among theN time-domain symbols. It is assumed in FIGS. 8a and 8b that the basestation and the terminal agree that the value of N belongs to {1, 2}.The terminal can blindly detect whether FIG. 8a or FIG. 8b is used bythe base station for transmission. In a determined time-domain resource,the terminal first detects DCI information (that is, the common controlsignaling) in the time-domain symbol having the smallest index. In thesecond implementation, the common control signaling can occupy resourcesin the N time-domain symbols, as shown in FIG. 8c , where the value of Nis 2. In this case, the common control signaling in each transmissionresource can occupy resources in two time-domain symbols. The DCI in thetwo symbols may be the same DCI that are repeatedly transmitted or maybe different indication fields of the same DCI.

In an embodiment, the common message includes at least one of thefollowing: a system message, a paging message, a random access response(RAR) message, a radio resource control (RRC) message and a TransmissionPower Control (TPC) message. In this embodiment, the transmission beamgroup i is the transmission resource i, where the value of i is a valuein the set {0, 1, . . . , M−1}.

Embodiment Two

In this embodiment, the common control information is transmitted on Mtime-domain resources through M transmission resources, where each ofthe time-domain resources includes N time-domain symbols. The commoncontrol information and a measurement reference signal are transmittedin the N time-domain symbols in one time-domain resource.

The common control information and the measurement reference signal aretransmitted in the N time-domain symbols in one time-domain resource asdescribed below. In the first manner, the measurement reference signaland the common control information are in time-division multiplexingmode, and the measurement reference signal is transmitted before thecommon control information, or the total number of repeatedtransmissions of the measurement reference signal is greater than orequal to the total number of repeated transmissions of the commoncontrol information. For example, the total number of repeatedtransmissions of the measurement reference signal is R and the totalnumber of repeated transmissions of the common control information is 1,that is, the receiving manner is first trained and the common controlinformation is received in the optimal receiving manner. As shown inFIG. 9a , the measurement reference signal is transmitted before thecommon control information, and the common control information includesat least one of C-CCCH and C-PDSCH. The time-domain resource fortransmission resource 0 is composed of R measurement reference signalresources for transmission resource 0 and common control informationresources for transmission resource 0.

When the common control information is at least one of a paging messageand a control signaling indicating configuration information about thepaging message, the total number of repeated transmissions of themeasurement reference signal may be different in different pagingopportunities. That is, in one time-domain resource, the total number ofrepeated transmissions of the measurement reference signal may be themaximum number of receiving manners corresponding to all users to whichpaging can be transmitted in the paging opportunity or may be themaximum number of receiving manners corresponding to all users includedin the currently transmitted paging message in the paging opportunity.The paging opportunity has the M time-domain resources. As shown inFIGS. 9b and 9c , the total number of repeated transmissions of themeasurement reference signal in the first paging opportunity of a basestation is 4. As shown in FIG. 9b , the total number of repeatedtransmissions of the measurement reference signal in the second pagingopportunity of the base station is 8. As shown in FIG. 9c , the pagingopportunity of the user group 1 may be transmitted in the first pagingopportunity, and the paging opportunity of the user group 2 may betransmitted in the second paging opportunity.

The total number of repeated transmissions of the measurement referencesignal in each paging opportunity may be determined according to themaximum number of receiving manners among the users that can be paged inthe paging opportunity. For example, the paging message of the usergroup 1 may be transmitted in the first paging opportunity, and the usergroup 1 includes {user 1, user 2, user 3, . . . , user 10}. The 10 usershave different user IDs. The total number of receiving mannerscorresponding to these 10 users is {(user 1, 1 receiving manner), (user2, 2 receiving manners), (user 3, 4 receiving manners), . . . , (user10, 1 receiving manner)}. Assuming that the maximum number of receivingmanners of the 10 users is 4, in this solution, if the users do notchange in the next paging opportunity, in one paging opportunitycorresponding to one user group, transmission beams transmitted atdifferent times have the same number of repetitions.

The second solution of the total number of repeated transmissions of themeasurement reference signal in each paging opportunity is determinedaccording to the maximum number of receiving manners of the currentlypaged users. For example, in the first paging opportunity as describedabove, the user group 1 can be paged. The user group 1 includes {user 1,user 2, user 3, . . . , user 10}. The currently paged are user 1 anduser 2. The total number of receiving manners of user 1 and user 2 is(user 1, 1 receiving manner), (user 2, 2 receiving manners). In thiscase, in this paging opportunity, the total number of repeatedtransmissions of the measurement reference signal is the maximum numberof receiving manners of user 1 and user 2, and the total number ofrepeated transmissions of the measurement reference signal is 2. In thepreceding solution, a terminal feeds back the user receiving mannercapability (for example, the total number of receiving manners) to thebase station.

In the preceding solution of transmitting the measurement referencesignal, different transmission resources are polled, and then thetransmission resources are repeatedly transmitted. The solution iscompatible with terminals having different receiving manners.

As shown in FIG. 9b , if user 2 has two receiving manners, user 2 can bewoken up in two scanning periods of the measurement reference signalbefore the common control information; if user 4 has four receivingmanners, user 4 can be woken up in four scanning periods of themeasurement reference signal before the common control information. Inthe preceding implementation, a demodulation reference signal may not betransmitted while the common control information is transmitted, and themeasurement reference signal may serve as the demodulation referencesignal. For example, in FIGS. 9a to 9c , the C-CCCH/C-PDSCH domain doesnot include the demodulation reference signal, the terminal acquires theoptimal transmission resource (abbreviated as TRS in FIG. 9a to 9c ) andreceiving manner in the measurement reference signal domain, and themeasurement reference signal corresponding to the optimal transmissionresource and receiving manner may serve as the demodulation referencesignal of the transmission resource and receiving manner correspondingto the common control information domain.

As shown in FIG. 9a , if user 2 obtains transmission resource 0 andreceiving manner 1 in the 8th scanning period of the measurementreference signal described in the figure, then the demodulationreference signal of transmission resource 0 of user 2 in theC-CCCH/C-PDSCH domain may be the measurement reference signal resourceof transmission resource 0 in the 8th scanning period. The measurementreference signal may be used as the demodulation reference signal if atleast one of the following conditions is satisfied: the interval betweenthe measurement reference signal resource and the common controlinformation resource is small, and the total number of time domainresources required by one beam scanning is small. If the precedingcondition is not satisfied, the measurement reference signal is not usedas the demodulation reference signal, or the use of the measurementreference signal as the demodulation reference signal needs to beindicated by signaling. In one time-domain symbol, the signaling may betransmitted before the M time-domain resources.

The common control information and the measurement reference signal aretransmitted in N time-domain symbols in one time-domain resource asdescribed below. In a second manner, the measurement reference signaland the common control information are in frequency-divisionmultiplexing mode, and the measurement reference signal and the commoncontrol information are repeatedly transmitted. Optionally, themeasurement reference signal is used a demodulation reference signal.

Optionally, when the common control information includes at least one ofa paging message and a control signaling indicating configurationinformation about the paging message, for the total number of repeatedtransmissions of the measurement reference signal and the common controlinformation, reference can be made to the total number of repeatedtransmissions of the measurement reference signal and the common controlinformation described above. The total number of repeated transmissionsmay be the maximum number of receiving manners of all users that cantransmit paging message in the paging opportunity or may be the maximumnumber of receiving manners of all users involved in the currentlytransmitted paging message in the paging opportunity.

When terminals corresponding to different information in the commoncontrol information have different numbers of receiving manners, onemanner is that R repeated transmissions correspond to the sameinformation and the other manner is to classify information according tothe total number of receiving manners, that is, information having thesame number of receiving manners has the same number of repeatedtransmissions. For example, the common message is a paging message, thepaging message includes paging information of terminals 1 to 4, and theterminal 1, terminal 2 terminal 3 and terminal 4 have 1 receivingmanner, 2 receiving manners, 2 receiving manners and 4 receiving mannersrespectively. If the paging message is transmitted on 4 time-domainsymbols, then the paging message of the terminal 1 is only transmittedon one symbol, the paging message of the terminal 2 is transmitted ontwo symbols, the paging message of the terminal 3 is transmitted on twosymbols, and the paging message of the terminal 4 is transmitted on 4symbols. As a result, among the 4 time-domain symbols, one time-domainsymbol is used to transmit 4 users' paging messages, 2 time-domainsymbols are used to transmit 3 users' paging messages and onetime-domain symbol is used to transmit 4 user's paging messages. Thepaging messages transmitted sequentially in the time domains of the 4symbols include sequentially decreased or increased paging elements. Onepaging element in one paging message corresponds to the identifier ofone user.

As shown in FIG. 9d , in the repeated time division transmissions of thesame transmission resource, the paging information transmitted in eachtime-division resource is different. User l's paging message is onlytransmitted on one time-division resource, and user 4's paging messageis transmitted on 4 repeated resources. In this case, the user 4searches for the paging message by using different receiving manners onthe 4 time-division resources, but the paging messages on differenttime-division resources have different lengths.

In a first solution, on each time-division resource, the common controlsignaling indicates the resource occupied by the paging message and thelength information of the paging message. In a second solution, thecommon control information does not include the common controlsignaling, and only the paging message is transmitted. In this case, theterminal performs blind detection among the lengths of multiple pagingmessages on each time-division resource. A third solution is to transmitpaging messages in blocks, and each block includes a fixed number ofpaging message lengths.

A receiving end obtains, by using a terminal identification signal, theblind detection range of the paging message at the receiving end. Asshown in FIG. 9e , each terminal detects the same length of pagingmessage on different time-division resources for repeated transmission.In this case, each terminal can obtain the detection range of its pagingmessage through the corresponding Temporary Mobile Subscriber Identity(TMSI) information.

For example, a user group involved in one paging opportunity includes{user 1 to user 10}, the 10 users are divided into 4 groups, and thesame group of users use the same search space for detecting pagingmessages or use the same scrambling information for detecting pagingmessages. The search space for detecting the paging message by a user isobtained according to at least one of the user identification number andthe total number of receiving manners. The user identification numbermay be UE_ID information in LTE. For example, the UE_ID information isobtained according to TMSI information.

In the preceding implementation, one basic block may include multipleusers, the total number of currently paged users may be small, and theterminal may also blindly detect the length of the paging message in onegroup. In FIG. 9e , different terminals occupy the same position onmultiple time-division resources for repeated transmission. Differentterminals may occupy hopping frequency-domain positions on multipletime-division resources for repeated transmission. FIGS. 9d to 9e showthe manner of repeated transmission of the transmission resource 0. Thetransmission resource 1 to transmission resource (M−1) may also use thismanner of repeated transmission.

Embodiment Three

This embodiment relates to the number of aggregation degrees and thetotal number of search spaces. In this embodiment, common controlinformation is transmitted on M time-domain resources, each time-domainresource includes N time-domain symbols, and the common controlinformation includes at least one of the following: a common message anda common control signaling. The common control signaling is used forindicating configuration information about the common message.

In a first implementation, each of the M time-domain resources includesa first type of common control information, and the first type of commoncontrol information includes a common control signaling and a commonmessage, where the common control signaling indicates transmission ofthe common message. As shown in FIGS. 8a to 8c , the common controlsignaling corresponds to a specific aggregation degree, and the totalnumber of candidate control channel resources per aggregation degree isL.

Optionally, the time-domain resource satisfies at least one of thefollowing conditions: in a set of time-domain resources, the coding rateof the common control information is fixed; and in one time-domainresource, one common control information corresponds to one aggregationdegree and the aggregation degree is fixed. The aggregation degree isfixed, that is, the total number of time-frequency domain resourcesoccupied by one common control signaling is fixed. The total number ofcandidate control channel resources included in one search space peraggregation degree is 1, that is, one aggregation degree corresponds toone candidate control channel, that is, the time-frequency resourcesoccupied by the common control signaling are fixed.

In a second implementation, an aggregation degree corresponding to onecommon control information in one time-domain resource or the totalnumber of candidate control channel resources in one search space peraggregation degree is determined by at least one of the following: amanner of being notified by common control information: a manner ofbeing determined by a system bandwidth; and a manner of being determinedby the total number of demodulation reference signal ports correspondingto the one time-domain resource.

For example, the aggregation degree is {4 Control Channel Elements(CCEs), 8 CCEs}. An aggregation degree of 4 CCEs correspond to 2candidate control channel resources. There is one candidate controlchannel resource in the candidate control channels corresponding to anaggregation degree of 8 CCEs. The time-frequency resources in thecandidate control channel resources under the two aggregation degreesmay overlap, reducing terminal demodulation complexity. The CCE may be abasic mapping unit of a control channel in LTE.

In a second implementation, each of the M time-domain resources includesa second type of common control information, and the second type ofcommon control information includes only a common message. The length ofthe common message in the second type of common control message may bevariable, such as a paging message. The base station dynamicallydetermines the transmission length of the paging message according tothe current demand, that is, the paging message may include paging ofone user, and may also include paging of multiple users.

Assuming that the length of the second type of common controlinformation is variable, the terminal can blindly detect lengths ofmultiple common message. If time-domain resources corresponding to thecommon message having different lengths include different values of N,the terminal can perform blind detection in the case of differentassumed values of N, that is, the terminal can blindly detect the lengthof the common message and the value of N included in each time-domainresource separately.

Optionally, the ranges of blind detection may be different if the valuesof N and the lengths of the common message change. For example, if thevalue of N is 1, the blind detection range of the length of the commonmessage is a length set 1 {length 1, length 2}; if the value of N is 2,the blind detection range of the length of the common message is alength set 2 {length 3, length 4}. Optionally, the length in {length 3,length 4} is greater than the length in {length 1, length 2}.Optionally, the maximum value of the length in {length 3, length 4} isgreater than the minimum value of the length in {length 1, length 2}.

An intersection may be existed between the length set 1 and the lengthset 2. For example, the common message is a paging message, and thelength of the paging message is a length before the channel coding ofthe paging message. The length before the channel coding may cause thetotal number of occupied time-frequency resources after the channelcoding to be different.

In the second implementation in which only the common message istransmitted and the length of the common message is variable, the searchspace of the paging message of the user may be obtained according to theterminal identification number. This improves the resource utilizationrate and the blind detection range of the length of the paging message.

As shown in FIG. 9f , multiple paging messages (abbreviated as PMS inFIG. 9f ) can be simultaneously transmitted on each time-domainresource, and multiple users can be paged in one paging message. In onetime-domain resource, multiple paging messages can be distinguished fromeach other by the detection range of the paging message and thescrambling manner of the paging message. The detection range of thepaging message and the scrambling manner of the paging message can beobtained according to the terminal identification number.

In an example, one paging opportunity corresponds to user 1 to user 40,and the users are divided into four groups {user 1 to user 10}, {user 11to user 20}, {user 21 to user 30}, and {user 31 to user 40}. The fourgroups sequentially correspond to the paging message 0 to the pagingmessage 3 in FIG. 9f . In FIG. 9f , the frequency-domain resourcescorresponding to the same paging message in the M time-domain resourcesare fixed. In an embodiment, the frequency-domain resourcescorresponding to the same paging message in the M time-domain resourcesmay hop in a certain manner. For example, the search space of one pagingmessage in one time-domain resource is determined according to an indexof the time-domain resource and an index of the paging message.Different paging messages in one time-domain resource in FIG. 9f are infrequency-division mode.

The detection spaces of different paging messages can also overlap inthe frequency domain. At least one of the following information of eachpaging message is blindly detected: the length of the paging message,the aggregation degree of the paging message, and candidate controlchannel resources per aggregation degree. One paging opportunityconsists of the M time-domain resources, and one paging opportunity mayalso occur periodically. The common message on the paging opportunitycan be transmitted as needed. The paging opportunity is similar to atype of subframe determined by (PF, i_s) in LTE. Each subframe in thistype of subframe corresponds to the M time-domain resources herein.

In a third implementation in which only the common message istransmitted and the length of the common message is variable, pagingmessages are divided into basic units, each of the units includes apaging message and a control signaling, and the signaling indicates atleast one of the following information: indicating whether the currentunit is the last unit, indicating the unit index of the current unit,the total number of units, the time-frequency domain resources where thenext unit is located, and a sub-block of the common message. Optionally,each of the basic units corresponds to the same number of bits, reducingthe complexity of blind detection of the terminal.

Embodiment Four

This embodiment describes the distribution of physical positions of M*Ntime-domain symbols.

In a first implementation, M*N time-domain symbols are in T1 consecutivesubframes, and M*N time-domain symbols occupy the entire subframe ineach subframe. For example, if M*N=56 and each subframe includes 14time-domain symbols, then 56 time-domain symbols occupy 4 consecutivesubframes, occupying 14 time-domain symbols in each subframe, that is,symbols in each subframe are all occupied by time-domain symbols onwhich common control information is transmitted.

In a second implementation, M*N time-domain symbols are in T1consecutive subframes, and M*N time-domain symbols occupy part oftime-domain symbols in each subframe and do not occupy the entiresubframe in each subframe. For example, if M*N=56 and each subframeincludes 14 time-domain symbols, then 56 time-domain symbols occupy 8consecutive subframes, occupying 7 time-domain symbols in each subframe,that is, symbols in each subframe are partially occupied by time-domainsymbols on which common control information is transmitted. Theremaining symbols can be used to transmit general service data andprivate control information.

In a first implementation, M*N time-domain symbols are in T1 discretesubframes, and M*N time-domain symbols occupy the entire subframe ineach subframe. For example, if M*N=56 and each subframe includes 14time-domain symbols, then 56 time-domain symbols occupy 4 discretesubframes, occupying 14 time-domain symbols in each subframe, that is,symbols in each subframe are all occupied by time-domain symbols onwhich common control information is transmitted. The discrete 4subframes are preferably equally spaced or distributed according to acertain rule.

In a second implementation, M*N time-domain symbols are in T1 discretesubframes, and M*N time-domain symbols occupy part of time-domainsymbols in each subframe and do not occupy the entire subframe in eachsubframe. For example, if M*N=56 and each subframe includes 14time-domain symbols, then 56 time-domain symbols occupy 8 discretesubframes, occupying 7 time-domain symbols in each subframe, that is,symbols in each subframe are partially occupied by time-domain symbolson which common control information is transmitted. The remainingsymbols can be used to transmit general service data and private controlinformation. The discrete 8 subframes are preferably equally spaced ordistributed according to certain rules.

When the total number of time-domain symbols for transmitting commoncontrol information in one subframe is less than the total number oftime-domain symbols included in the subframe, for example, when thetotal number of symbols allocated to common control information in onesubframe is less than the total number of the time-domain symbolsincluded in the subframe or when all M time-domain resourcescorresponding to common control information fail to occupy the entiresubframe, common control information in one subframe may be at the endof the downlink transmission domain of one subframe, as shown in FIG.10a ; or common control information in one subframe is all at thebeginning of the downlink control domain (abbreviated as DCD in FIG. 11a), as shown in FIG. 11a ; or one part is at the beginning of thedownlink control domain and another part is at the end of the downlinktransmission domain, as shown in FIG. 10b , for example, M1 commoncontrol information are at the beginning of the downlink control domainof the subframe and M2 common control information are at the end of thedownlink transmission domain of the subframe, in which case M1time-domain resources are all in the downlink control domain; or the M1time-domain resources include the downlink control domain and the datatransmission part, where the common control signaling in the M1time-domain resources is in the downlink control domain and the commoncontrol signaling may indicate time-frequency resources where the commonmessage is located, where the common message may occupy time-frequencyresources in the data domain, as shown in FIG. 10 c.

For the manner in FIG. 10b or FIG. 10c , for example, that is, among Mtime-domain resources corresponding to common control information, M3time-domain resources need to be transmitted in one subframe, where M=M3or M3<M. The indexes of the M3 transmission resource are known to areceiving end, M1 time-domain resources in the M3 time-domain resourcesare transmitted in the downlink control domain, and the remaining M2time-domain resources are transmitted in the downlink transmissiondomain. The indexes of the M1 transmission resources transmitted in thedownlink control domain are dynamically changed and transmitted asneeded. A terminal first detects M1 time-domain resources in thedownlink control domain, and determines M1 transmission resourcestransmitted thereon, and each of the remaining M2 transmission resourcesis transmitted on M1 time-domain resources of the M2 time-domainresources.

Embodiment Five

In this embodiment, the transmission manner of common controlinformation is determined according to the type of the common controlinformation or determined according to the total number of symbolsrequired by the common control information.

For example, the total number of time-domain symbols required by thecommon control information is 14, and M=14, N=1, then the common controlinformation can be transmitted in a third transmission manner as shownin FIG. 11a or in a fourth transmission manner as shown in FIG. 11b orFIG. 11c . In FIG. 11a , transmission of a common message is indicatedby a common control signaling. The common message and general servicedata can be in frequency-division multiplexing mode, and the commoncontrol signaling and a private control signaling can be infrequency-division multiplexing mode, which is similar to the manner ofSystem Information Blocks (SIB), Paging. RAR or TPC in LTE.

The subframe in which the common message is transmitted does not requirespecial processing, and the common message can be transmitted in anysubframe. The common control information is transmitted by using adedicated time-domain symbol set in FIG. 11b or FIG. 11c . Optionally,the private control signaling and the common control signaling are intime-division multiplexing mode. Optionally, the common message andservice data are in time-division multiplexing mode, and specialprocessing is performed for the structure of the subframe in which thecommon message is transmitted. Optionally, the common message can appearin only a specific subframe and does not appear in all subframes.

In this embodiment, one manner is to determine whether to use the thirdtransmission manner or the fourth transmission manner according to thetotal number of time-domain symbols required by the common controlinformation. For example, if the total number of M*N is lower than apredetermined threshold, the third transmission manner is used, and ifthe total number of M*N is not lower than the predetermined threshold,the fourth transmission manner is used. The value of M may be determinedaccording to the total number of time-domain symbols of asynchronization signal, and the value of N is determined according tothe size of the content of the common control information. The value ofM*N is the total number of time-domain symbols required by the commoncontrol information. The predetermined threshold is obtained accordingto the total number of time-domain symbols included in a dedicatedcontrol channel.

One manner is to determine whether to use the third transmission manneror the fourth transmission manner according to the type of the commoncontrol information. For example, when the delay requirement for thecommon message is relatively high, the third transmission manner isused, so that the common control information is transmitted as needed inany subframe. For example, when the common message is RAR or TPC (thesecommon messages may also be referred to as group common controlmessages, because their target users are not users in the entire cell,but part of the users; these common messages may be transmitted by usingpart of transmission resources, and not by using all beams to achievecell coverage), the third transmission manner is used: when the commonmessage is Paging or SIB, the fourth transmission manner is used.

In this embodiment, the transmission manner of the common controlinformation is determined according to the type of the common controlinformation: and it is determined whether to use the common controlsignaling to indicate transmission of the common message or to onlytransmit the common message according to whether the message length ofthe common control information is fixed or variable. For example, if themessage length of the common control information is fixed, only thecommon message is transmitted: if the message length of the commoncontrol information is variable, the common control signaling is used toindicate transmission of the common message.

In this embodiment, the transmission manner of the common controlinformation is determined according to the type of the common controlinformation; and it is determined whether to use the common controlsignaling to indicate transmission of the common message or to onlytransmit the common message according to the message length of thecommon control information. For example, if the length is short, onlythe common message is transmitted; if the length is long, the commoncontrol signaling is used to indicate transmission of the commonmessage.

In this embodiment, the transmission manner of the common controlinformation is determined according to the type of the common controlinformation; and it is determined whether to use the common controlsignaling to indicate transmission of the common message or to onlytransmit the common message according to whether the common controlinformation is transmitted as needed. For example, if the message lengthof the common control information is fixed, only the common message istransmitted; if the common control information is transmitted as needed,the common control signaling is used to indicate transmission of thecommon message.

In this embodiment, the transmission manner of the common controlinformation is determined according to the type of the common controlinformation; and it is determined whether to use the common controlsignaling to indicate transmission of the common message or to onlytransmit the common message according to delay requirements of thecommon control information. For example, the common message with a lowdelay requirement is transmitted in the fourth transmission manner shownin FIG. 11b or FIG. 11c ; the common message with a high delayrequirement is transmitted in the third transmission manner shown inFIG. 11a . When the common control information corresponds to multipletime-domain resources, the common control information is transmitted inmultiple subframes as shown in FIG. 11a . In FIG. 11a , the commonmessage requires 14 OFDM symbols. Since only two OFDM symbols exist inthe downlink control domain in each subframe, the common controlinformation is transmitted in 7 subframes. If the total number oftime-domain symbols required by the common control information is lessthan or equal to two, the common control information may also betransmitted in one subframe.

Embodiment Six

In this embodiment, for each value of N, a terminal obtains thetime-domain symbol position where the set of time-domain resources islocated, logically numbers the M*N time-domain symbols 0, . . . ,M*(N−1) by time, and determines N time-domain symbols included in eachtime-domain resource by using one of the manners described below.

In a first implementation, the N time-domain symbols corresponding tothe ith transmission resource are logically numbered as i*N+j, j=0, 1,1, where 0≤i≤M−1.

In a second implementation, the N time-domain symbols corresponding tothe ith transmission resource are M*n+i, where 0≤i≤M−1, 0≤n≤N−1.

Embodiment Seven

In this embodiment, each of M time-domain resources includes a differentnumber of time-domain symbols.

For example, when common control information and private controlinformation are in frequency multiplexing mode, different time-domainresources require different time-domain symbols. For example, sometime-domain resources have private control information, and sometime-domain resources do not have private control information.

The receiving manner includes one or more of the following: a receivingbeam, a receiving port, a receiving antenna, receiving time, a receivingfrequency domain, the maximum number of receiving manners of thereceiving end, or the total number of different receiving manners usedto receive the same time-domain resource.
